SPRING-RING SHADE-HOLDER.

Specification of Letters Patent.

Patented Mar. 1'7, 1914..

Application filed July 16, 1912. Serial No. 709,776. Renewed December15, 1913. Serial No. 806,882.

To all whom it may concern Be it known that I, THOMAS J. LITLE, Jr.,

I a resident of VVoodbury, in the county of ring holders for lobes orshades, and espe-- cia-lly to the slot in the flange of the burner forreceiving the supporting loop at the opposite side of the spring ringholder from that of the handles.

The object of the invention is to provide a very simple and efficientmeans for holding the wire loop in this slot;

To that end the invention consists in so shaping and arranging the loopand walls of the slot'relatively to each other through which the loopextends. that the loop may b iillowed movement within the slot duringoperating (contracting and expanding), while, at the same time removalor slipping out of the loop from the slot is prevented when the partsare in their normal arrangement and relation to each other; it alsoconsists in the form shown in roviding the slot with a centralrestricted portion which, when brought to position, will retain the loopor U-shaped projection of the spring 1 ring in position.

In the drawing. 2 represents an inverted incandescent gas burner havingthe usual depending flange 3.. Thls flange is preferably grooved orrecessed and receives the spring ring holder 4. Thi is formed of springwire in one piece with a U -shaped supporting portion 5 at one side,which projects throu h a slot 6 in the burner flange.

This slot is provided with acentral restricted portion 7 shown as in-theform of a holding member, which extends into or across the slot.. Thisrestricted portion is preferably formed in the cutting of the slot andmay be bent back for'insertion of the loop and then bent into positionto restrictthe central portion of the slot and hold the" Q-shapedprojection or loop of the spring ring holder.

The spring ring holder may be of any de sired form and may not either bycontraction or expansion. In the form shown, it normally expands and itsprojecting handles 8, 8, pass through slots 9, 9, having hooks 10, toreceive them when pressed into holding position. I have shown the wireas sup ported on swinging side loops or arms 10 within the burner,though this may or may not be so, as desired.

The advantages of the invention result from the use of the restrictedcentralportion of the slot for the U-shaped projection of the springring holder. The device is easily and cheaply made, :as the slot may beformed and opened up to receive the U-' shaped projection and thecentral portion then bent anywhere to contract the space and retain thewire in position. In assembling, the handle portions will he slippedthrough their slots, the U-shaped projection will he slipped through itsslot, and the prong, forming the contraction, will be then bent intoplace, thus holding the U-shaped projection securely in position whileallowing it to yield or move slightly to aid in centering the globe.

The spring ring may act by contraction or expansion, the handles andslots therefor may be changed, and other changes may be made withoutdeparting from the spirit of my invention, a defined in theappendedclaims.

I claim:

1. In a shade or globe holder, an annular annular flange through whichsaid projec-' tion is adapted to extend, said slot being provided with acentral restricted port-ion adapted to be positioned to retain saidprojection in engagement with said flange, said ring-like element havingits ends otfsctto form operating handles, and a second and elongatedslot formed in said annular flange through which said handles pass tothe outside of the flange; substantially as described.

2. In a shade or globe holder, an annular flange, a ring-like wire shaderetaining element having a pro ection ad acent to its middle portion,the annular flange having:

a slotthrough which said projection is adalpted to extend, saidslotbeing provided wit a central restricted portion arranged to retainsaid projection in engagement with said annular flange through which theloop ment is in its normal copies of this patent may be obtained to!said flange, the ring-like wire retaining element. having operatinghandles; substan-- tiallya's described. A a

3. A shade or globe holder having an annular flange, a' ring-like wireshade retaining element havin a loop in its intermediate portion, thereeing a slot formed inthe ing element having a loop in its intermediateportion, there being an openin formed 'in the said annular flange throngwhich the loop extends, the opening being shaped to permit the loop tomove a predetermined distance to prevent removal of'the loop when theshade retaining element is in its normal position within the shadeholder; substantlall as described.

5.. A sha e or globe holder having an an I nular flange, a ring-likewire shade retaining element having a loop in its interme-' diateportion, there being an opening formed in said annular flange throughwhich the loop extends, and a-holding member coacting with the openingto prevent the loop from accidental displacement from the slot,

.While allowing some movement of said loop;

substantially as described.

In testimony whereof, I have hereunto set my hand.
